This application is based on Japanese Patent Application No. 2013-77249 filed on April 2, 2013, the disclosure of which is incorporated herein by reference.

This disclosure relates to an input device that performs input for information display on a display unit by an operator's finger operation.

As a conventional input device, for example, the one disclosed in Patent Document 1 is known. In the input device (operation user interface device) of Patent Document 1, a remote touchpad unit for a user to perform a touch operation, and various modes of the multimedia system according to a three-dimensional signal received from the remote touchpad unit. A display unit for displaying and a control unit for controlling the multimedia system to operate according to the three-dimensional signal of the remote touchpad unit are provided.

JP 2011-118857 A

However, according to the study of the present inventor, in the above-mentioned Patent Document 1, it is difficult to intuitively understand the current finger height position and the operation content corresponding to the finger height position. In some cases, it is difficult to know at what height the finger is currently located and what operation can be performed on which screen.

The present disclosure has been made in view of the above, and it is an object of the present disclosure to provide an input device that can intuitively grasp the position of a finger with respect to an operation surface and easily determine an operation procedure for an image.

The input device according to an example of the present disclosure adopts the following configuration.

The input device is mounted on the vehicle and formed separately from the display unit that displays the images divided into a plurality of layers in a switchable manner, and operates the image by a user's finger operation on the operation surface. It is an input device in which input is performed. The input device detects the operation state of the finger with respect to the operation surface during the finger operation, and the determination on the operation state detected by the detection unit is close to the operation surface with respect to the contact state in contact with the operation surface A control unit that stereoscopically displays a planar image on the display unit when in the proximity state;

According to such an input device, when the user's finger is in the proximity state when operating the image, the original planar image is displayed three-dimensionally by the control unit. Therefore, the user can intuitively grasp that the finger has not yet reached the operation surface and is not in a state where it can be operated by touching the operation surface. In addition, when the finger is in contact with the proximity state, the image becomes an original flat display that does not hinder the finger operation. Therefore, since the user can easily grasp the proximity state or contact state of the finger with respect to the operation surface depending on whether the image is three-dimensional or planar, the operation procedure for the image can be easily discriminated. Never get lost.

(First embodiment)
In the first embodiment (FIGS. 1 to 7), the input device of the present disclosure is applied to a remote operation device 100 for operating a navigation device 50. FIG. The remote operation device 100 is mounted on a vehicle and constitutes the display system 10 together with the navigation device 50 and the like.

As shown in FIGS. 1 and 2, the remote control device 100 is installed at a position adjacent to the palm rest 39 at the center console of the vehicle, and is within the reach of the operator (user and driver here). The operation surface 32 is exposed in an easy range. The remote operation device 100 includes a touch sensor 31, and the surface of the touch sensor 31 is formed as the operation surface 32 on which an operator's finger operation is performed. Note that “F” in FIG. 1 indicates an operator's finger.

In addition, the navigation device 50 exposes the display screen 53 of the liquid crystal display 52 so that it can be viewed by the operator, and with the display screen 53 facing the driver's seat and the passenger's seat side, It is installed in the center of (vehicle width direction). The display system 10 (liquid crystal display 52) switches and displays various display images 60 on the display screen 53. The remote control device 100 is formed separately from the navigation device 50 and is set at a position away from the navigation device 50.

Hereinafter, each configuration of the remote operation device 100 and the navigation device 50 will be described in detail with reference to FIG.

The remote operation device 100 is connected to a Controller Area Network bus (hereinafter referred to as a CAN bus) 90, an external battery 91, and the like. The CAN bus 90 is a transmission path used for data transmission between in-vehicle devices in an in-vehicle communication network formed by connecting a plurality of in-vehicle devices mounted on a vehicle. The remote operation device 100 can communicate with the navigation device 50 located remotely via the CAN bus 90.

The remote operation device 100 includes

power interfaces

21 and 22, a communication control unit 23, a communication interface 24, a touch sensor 31, an operation surface 32, an operation control unit 33, and the like. Each

power supply interface

21, 22 stabilizes the power supplied from the battery 91 and supplies it to the operation control unit 33. One power interface 21 is always supplied with power from the battery 91. The other power interface 22 is supplied with electric power from the battery 91 when the switch 92 is energized when the accessory (ACC) power source of the vehicle is turned on.

The communication control unit 23 and the communication interface 24 are configured to output information processed by the operation control unit 33 to the CAN bus 90 and to acquire information output to the CAN bus 90 from other in-vehicle devices. The communication control unit 23 and the communication interface 24 are connected to each other by a transmission signal line TX and a reception signal line RX.

The touch sensor 31 is a capacitance type detection unit (an example of a detection unit), is formed in a rectangular flat plate shape, and detects an operation state with a finger on the sensor surface. The touch sensor 31 is formed by arranging electrodes extending along the x-axis direction and electrodes extending along the y-axis direction in a lattice shape. These electrodes are connected to the operation control unit 33. Each electrode is configured such that the generated capacitance changes according to the position of the finger close to the sensor surface (x, y, z coordinate position in FIG. 2). A signal (sensitivity value) is output to the operation control unit 33. The sensor surface is covered with an insulating sheet made of an insulating material.

The operation surface 32 is a flat portion on which the operator performs finger operations, and is formed by, for example, a material that improves the sliding of the fingers over the entire insulating sheet on the sensor surface. Input for operation on the display image 60 (see FIG. 7) displayed on the display screen 53 can be performed by an operator's finger operation on the operation surface 32 in the x-axis direction, the y-axis direction, or the z-axis direction. Is set.

The operation control unit 33 is a control unit of the present disclosure, and includes a processor that performs various types of arithmetic processing, a RAM that functions as a work area for arithmetic processing, and a flash memory that stores programs used for arithmetic processing. ing. In addition, the operation control unit 33 is connected to the power supply interfaces 21 and 22, the communication control unit 23, the touch sensor 31, and the like.

The operation control unit 33 acquires a sensitivity value (Hth) as a measurement value of the touch sensor 31 by measuring a capacitance signal of each electrode of the touch sensor 31 by executing a predetermined program. When the operator's finger is close to the operation surface 32 (sensor surface), electric charge is stored between the electrode and the finger. The operation control unit 33 includes an x-coordinate and a y-coordinate indicating a relative operation position (hereinafter referred to as “relative position”) of the finger in a direction in which the surface of the operation surface 32 spreads, and further, a distance from the operation surface 32 to the finger. The z coordinate corresponding to (hereinafter referred to as “operation distance”) is calculated by a calculation process based on the sensitivity value.

Specifically, as shown in FIG. 4, for example, when a finger is brought into contact with the electrode arranged in the x-axis direction on the operation surface 32 corresponding to the position of an arbitrary electrode portion, a large sensitivity value can be obtained. Since the contact state of the finger disappears as the position becomes farther from the contact position, the sensitivity value becomes smaller. The same applies to the electrodes arranged in the y-axis direction. Therefore, the operation control unit 33 calculates a part (x coordinate position, y coordinate position) where the greatest sensitivity value is obtained among the electrodes on the x axis and the y axis as the current relative position of the finger. ing.

In the z-axis direction, the sensitivity value increases as the finger approaches the operation surface 32, and conversely, the sensitivity value decreases as the finger moves away from the operation surface 32. Therefore, the operation control unit 33 calculates the current z coordinate position of the finger, that is, the operation distance, based on the magnitude of the obtained sensitivity value.

Further, as shown in FIGS. 4 and 5, the operation control unit 33 operates a finger operation state (finger operation distance in the z-axis direction) and an operation on a display image 60 described later with respect to the obtained sensitivity value. Associate actions. The operation control unit 33 includes a plurality of sensitivity threshold values Hth1 to Hth5 for determining the operation state in advance, and determines the operation state of the finger according to the sensitivity threshold value. The operation state includes a “contact state” in which the finger is in contact with the operation surface 32 or is not actually in contact but is almost in contact, and a “proximity state” in which the finger is in proximity to the operation surface 32. , And the “non-contact state” in which the finger is further away from the operation surface 32 than the “proximity state”. The “contact state” may be an operation state only when the finger substantially contacts the operation surface 32.

For example, the operation control unit 33 includes Hht1 = count200, Hht2 = count175, Hht3 = count150, Hht4 = count125, and Hht5 = count100 as sensitivity thresholds. If the sensitivity value is equal to or higher than Hth1 (200), the finger is determined to be in “contact state” with respect to the operation surface 32. If the sensitivity value is between Hth1 to Hth5 (200 to 101), it is determined that the finger is in the “proximity state” with respect to the operation surface 32. If the sensitivity value is Hth5 (100) or less, it is determined that the finger is in a “non-contact state” with respect to the operation surface 32. Hereinafter, the “contact state” is referred to as “in contact”, the “proximity state” is referred to as “in proximity”, and the “non-contact state” is referred to as “non-contact”.

In addition, regarding the “proximity state”, the operation control unit 33 sets “proximity 1” when the sensitivity value is Hth2 (175) or more, “proximity 2” when the sensitivity value is Hth3 (150) or more, and the sensitivity value is Hth4 (125). As described above, “proximity 3” is determined by dividing the “proximity state” into a plurality of “proximity 1 to 3 states”.

It should be noted that if the finger slightly moves up and down in the vicinity of each of the sensitivity thresholds Hth1 to Hth5, the operation control unit 33 results in repeated inversion (hunting). Therefore, the upper thresholds Hth1U to Hth5U corresponding to the positions separated by a predetermined distance are set above the sensitivity thresholds Hth1 to Hth5 (side closer to the operation surface 32). Further, lower thresholds Hth1D to Hth5D corresponding to positions separated by a predetermined distance are set below the sensitivity thresholds Hth1 to Hth5 (the side far from the operation surface 32), respectively. When the finger is moved from the lower side (far side) to the upper side (near side) of each sensitivity threshold Hth1 to Hth5, each upper threshold Hth1U to Hth5U becomes a sensitivity threshold for determining the operation state. . Conversely, when the finger is moved from the upper side (near side) to the lower side (far side) of each sensitivity threshold value Hth1 to Hth5, the lower threshold values Hth1D to Hth5D are used for determining the operation state. Sensitivity threshold.

Furthermore, the operation control unit 33 detects a pressing operation (touch operation) when the operator gently presses the operation surface 32 with a finger. Then, the operation control unit 33 outputs the x, y, z coordinates indicating the position of the finger accompanying the finger slide operation and the presence or absence of the pressing operation to the CAN bus 90 through the communication control unit 23 and the communication interface 24.

In addition to the navigation function for displaying the current position on the map and destination guidance, the navigation device 50 has an air conditioning operation setting function for the vehicle air conditioning device, an audio operation setting function for the vehicle audio, and various information retrieval via the Internet. It has a browsing function. The navigation device 50 is connected to the CAN bus 90 so as to be able to communicate with the remote operation device 100 and the like, and includes a display control unit 51 and a liquid crystal display 52.

Regarding the various functions described above in the navigation device 50, “Climate (air conditioner operation)”, “Map (map display)”, “Destination (destination setting) are set in a menu item 61 in a display image 60 of the liquid crystal display 52 described later. ”,“ Media (audio operation) ”,“ Network (Internet operation) ”, etc. (FIG. 7).

The display control unit 51 includes a processor that performs various arithmetic processes, a RAM that functions as a work area for arithmetic processes, a graphic processor that performs image drawing processes, a graphic RAM that functions as a work area for drawing processes, and the like. In addition, the display control unit 51 has a flash memory for storing data used for arithmetic processing and drawing processing, a communication interface connected to the CAN bus 90, and a video output interface for outputting drawn image data to the liquid crystal display 52. is doing. The display control unit 51 draws a display image 60 to be displayed on the display screen 53 based on information acquired from the CAN bus 90. The display control unit 51 sequentially outputs the image data of the drawn display image 60 to the liquid crystal display 52 through the video output interface.

The liquid crystal display 52 is a dot matrix type display unit that realizes color display by controlling a plurality of pixels arranged on the display screen 53. The liquid crystal display 52 displays video by continuously forming image data sequentially acquired from the display control unit 51 on the display screen 53.

The display image 60 displayed on the display screen 53 corresponds to an example of the image of the present disclosure, and is composed of images divided into a plurality of layers. For example, among the images of a plurality of layers, the image of the first layer (predetermined layer) is a plurality of main images for using various functions (navigation, air conditioner, audio, Internet, etc.) of the navigation device 50. . For example, FIG. 7 shows a main image for an air conditioner as one main image.

On the upper side of the display image 60, a menu 61 is provided in which a plurality of types (names) of main images are used as menu items and these menu items are arranged in the left-right direction. The menu 61 is always displayed in the same form regardless of the hierarchy of the display image 60. When the operator selects one of the desired menus 61 on the operation surface 32 by a finger operation, the selected main image is displayed on the display screen 53. Alternatively, the operator can scroll the main images sequentially by sliding the finger on the operation surface 32 without operating the menu 61 when any main image is displayed. The main image can be made.

Each main image is provided with a plurality of icons 62 for operating the image. In the example of FIG. 7, an air volume setting icon, a temperature setting icon, a dual setting icon, a blowing mode setting icon, etc. in the air conditioner operation are shown. When the operator selects a desired icon 62 by sliding a finger on the operation surface 32, a frame-shaped focus 63 indicating that the icon 62 has been selected is displayed. Further, when the finger is lightly pressed on the operation surface 32 so as to correspond to the position of the selected icon 62 (touch operation), the icon 62 is determined, and the image of the second hierarchy, that is, determined. The operation image corresponding to the icon is transferred, and various functions can be used in sequence.

Next, details of input processing from the touch sensor 31 by the operation control unit 33 will be described with reference to FIGS.

In FIG. 6, first, in step S100, an acquisition process for acquiring sensitivity values detected by each electrode of the touch sensor 31 is performed, and the process proceeds to step S110. In step S110, calculation processing of the x-coordinate indicating the relative position of the finger with respect to the operation surface 32, the y-coordinate, and the z-coordinate indicating the operation distance is performed from the sensitivity value acquired in step S100. Then, from the calculated value of the z coordinate indicating the operation distance, it is calculated whether the operation state of the finger is in contact, in proximity, or non-contact.

Specifically, when the sensitivity value detected by the touch sensor 31 is larger than Hth1 (Hth1U), during contact, and when the sensitivity value is between Hth5 (Hth5U) and Hth1 (Hth1D), during proximity, Furthermore, when the sensitivity value is smaller than Hth5 (Hth5D), it is calculated as non-contact.

Then, in step S120, it is determined whether the calculated finger operation state is not in contact and the sensitivity value is Hth1 or more (actually, the upper threshold value Hth1U or more). If an affirmative determination is made here, the operator's finger approaches the operation surface 32 from a non-contact or approaching state and is in contact with the operation surface 32. In step S130, the operation state of the finger is contacted. Update inside.

In step S140, the display screen 53 is updated to the in-contact screen. The in-contact screen is a screen on which the display image 60 is displayed on the display screen 53 as an original planar (no tilt) image, as shown in FIG. 7 (in the right frame). The focus 63 indicates the current operation state (operation setting state) of the device corresponding to the main image to be displayed.

In the contact screen, the operator can perform original screen operations, that is, selection and determination of each menu 61 and various icons 62 by finger operation (slide, touch operation, etc.). At this time, since the display image 60 is an original planar image, the operator intuitively knows that the finger operation state is in contact and the finger operation on each menu 61 and various icons 62 is possible. Can know.

Next, if it is determined NO in step S120, in step S150, the first condition is that the operation state is non-contact and the sensitivity value is Hth5 or higher (actually the upper threshold Hth5U or higher), or 2 As a first condition, it is determined whether or not the operation state is in contact and the sensitivity value is Hth1 or less (actually, the lower threshold value Hth1D or less). If an affirmative determination is made here, the operator's finger approaches the operation surface 32 from non-contact or is slightly away from the operation surface 32 during contact, and the operation state of the finger is approaching in step S160. Update to

In step S170, it is determined whether the sensitivity value is Hth2 or more (actually, the lower threshold value Hth2D or more). If an affirmative determination is made here, the operation state of the finger is in proximity and closer to the operation surface 32 (proximity 1), and the display screen 53 is updated to the proximity 1 screen in step S180. As shown in FIG. 7 (on the right side in the middle frame), the close one screen is a screen on which the display image 60 is displayed as a three-dimensional image with respect to the original planar image during contact. . A stereoscopic image is, for example, an image in which a portion of the original image is in a floating state and a portion corresponding to a shadow is formed below the floating image. Further, in the close one screen, the display image 60 is operated with respect to the display screen 53 because of the positional relationship between the liquid crystal display located substantially in the center in the width direction of the vehicle and the operator (the driver on the right side in this case). It is displayed in a shape inclined to the right side to some extent so as to face the person. Note that the focus 63 in the display image 60 is not displayed in the proximity 1 screen.

If a negative determination is made in step S170, it is determined in step S190 whether the sensitivity value is equal to or higher than Hth3 (actually, lower threshold Hth3D). If an affirmative determination is made here, the operation state of the finger is in the state of being close and slightly away from the operation surface 32 (proximity 2), and the display screen 53 is updated to the proximity 2 screen in step S200. The proximity two screen is a screen in which the display image 60 is displayed as a three-dimensional image as described in the above proximity one screen with respect to the original planar image during contact. Further, in the proximity two screens, the inclination of the display image 60 toward the operator is displayed in a shape inclined further to the right side than the image in the proximity one screen. In the proximity 2 screen, the focus 63 in the display image 60 is not displayed as in the proximity 1 screen.

If a negative determination is made in step S190, it is determined in step S210 whether the sensitivity value is equal to or higher than Hth4 (actually, lower threshold Hth4D). If an affirmative determination is made here, the operation state of the finger is in a state of being in proximity and far away from the operation surface 32 (proximity 3), and the display screen 53 is updated to the proximity 3 screen in step S220. As shown in FIG. 7 (left side in the middle frame), the proximity 3 screen is a display image 60 as described in the above proximity 1 screen with respect to the original planar image during contact. It is a screen displayed as a three-dimensional image. Further, in the proximity 3 screen, the inclination of the display image 60 toward the operator is displayed in a shape inclined further to the right side than the image in the proximity 2 screen. Note that the focus 63 in the display image 60 is not displayed on the three adjacent screens, as in the case of the close one screen. If it is determined NO in step S210, the flow ends.

In the above proximity 1 screen, proximity 2 screen, and proximity 3 screen, the operator can switch the main image by the menu 61 by a finger operation (gesture such as flick) during proximity. At this time, the operator can intuitively know that the position of the finger is in proximity (proximity 1 to proximity 3) from the three-dimensionally displayed display image 60. At the same time, as the tilt of the display image 60 is smaller, the operator is closer to the operation surface 32 (on the proximity 1 side), and conversely, the greater the tilt is, the farther the finger is from the operation surface 32. It can be intuitively known that it is on the (near 3 side).

Next, if it is determined as NO in step S150, it is determined in step S230 whether or not the operation state is non-contact and the sensitivity value is Hth5 or less (actually lower threshold Hth5D or less). If an affirmative determination is made here, the operator's finger is in a state of being greatly separated from the operating surface 32 from the contacted or approaching state, and the operation state of the finger is updated to non-contact in step S240. If it is determined NO in step S230, this flow ends.

In step S250, the display screen 53 is updated to a non-contact screen. As shown in FIG. 7 (in the left frame), the non-contact screen is a screen on which the display image 60 is displayed as an original planar image (without inclination), like the in-contact screen. A menu 61, various icons 62, and a focus 63 are displayed on the non-contact screen. The non-contact screen shows the current operating state (operation setting state) of the device corresponding to the main image to be displayed.

In the non-contact screen, the operator's finger is clearly separated from the operation surface 32, the operator has no intention to operate the display image 60, and the operator simply displays the display image 60 with the current device. It can be seen as a confirmation screen for confirming the operating state of

As described above, in the present embodiment, when the operator's finger is in the proximity state when operating the display image 60, the original planar display image 60 is stereoscopically displayed by the operation control unit 33. The Therefore, the operator can intuitively grasp that the finger has not yet reached the operation surface 32 and is not in a state where it can be operated by touching the operation surface 32. When the finger is in a contact state with respect to the proximity state, the display image 60 is an original planar display that does not hinder the finger operation. Therefore, the operator can easily grasp the proximity state or contact state of the finger with respect to the operation surface 32 depending on whether the display image 60 is three-dimensional or planar, so that the operation procedure for the display image 60 can be easily determined. It becomes possible and it will not be lost in operation.

In addition, the operation control unit 33 displays the display image 60 that is three-dimensional in the proximity state so that the display image 60 is inclined so as to face the operator (driver) side, and the display image 60 is displayed as the finger moves away from the operation surface 32. The display is made so that the inclination becomes large. Thereby, the operator can more clearly grasp whether the distance of the finger from the operation surface 32 is large or small by the inclination of the display image 60 with respect to the position of the finger in the proximity state.

Further, when the detected operation state is in a non-contact state that is further away from the proximity state than the operation surface 32, the operation control unit 33 is the same as the display image 60 displayed on the liquid crystal display 52 in the contact state. I try to make it a flat image. That the operation state is in a non-contact state is a case where the operator does not substantially perform a finger operation. In such a case, the display image 60 is changed to an original planar image, The operator can view the display image 60 without any trouble.

(Second Embodiment)
A remote operation device 100A of the second embodiment is shown in FIGS. In the second embodiment, as an operator, the display image 60 is input for a driver in a driver seat and a passenger seat in a passenger seat.

8 and 9, the remote operation device 100A is provided with

proximity sensors

34a and 34b. The proximity sensor 34 a is, for example, a sensor that is disposed on the right side of the operation surface 32 and detects that the driver's finger is approaching the operation surface 32 from the right side, and outputs the detected signal to the operation control unit 33. It is supposed to do. The proximity sensor 34b is, for example, a sensor that is disposed on the left side of the operation surface 32 and detects that a passenger's finger approaches the operation surface 32 from the left side. 33 is output. Therefore, the operation control unit 33 can determine whether the operator of the operation surface 32 is a driver or a passenger seat based on a signal from the proximity sensor 34a or the proximity sensor 34b.

As shown in FIG. 10, the flowchart of the input process performed by the operation control unit 33 is different from the flowchart (FIG. 6) described in the first embodiment whether the operator is a driver or a passenger. Steps S50, S51, and S52 for determining and setting the screen display according to the determination result are added.

In step S50, the operation control unit 33 determines whether the operator is a driver or a passenger seat from the output signals of the

proximity sensors

34a and 34b. Note that “D seat” in FIG. 10 means a driver seat, and “P seat” means a passenger seat.

If the operator is determined to be a driver in step S50, the operation control unit 33 performs screen display setting for the driver in step S51. The screen display setting for the driver is set to a basic form including each menu 61 and various icons 62 as the display image 60. If the operation state of the driver's finger is close, as shown in FIG. 11 (in the right frame), the display image 60 displayed in three dimensions is actually displayed in steps S180, S200, and S220. The setting is such that the image is tilted toward the operator operating the finger. As described in the first embodiment, the closer the driver's finger is to the operation surface 32 in proximity, the smaller the inclination of the stereoscopic image, and the further away the finger is from the operation surface 32, the greater the inclination of the stereoscopic image. Is displayed. When the driver is approaching, the main image can be switched by the menu 61 in the display image 60 by a finger operation (gesture such as flick).

At this time, the driver intuitively knows that the current display image 60 is based on the driver's own input since the three-dimensionally displayed display image 60 is tilted in the direction of his / her own. I can know. At the same time, as in the first embodiment, the smaller the inclination of the display image 60 displayed in a three-dimensional manner, the closer the finger is to the operation surface 32 (the proximity 1 side), and vice versa. It is possible to intuitively know that the finger is at a position away from the operation surface 32 (proximity 3 side).

If the operation state of the driver's finger is in contact, the operation control unit 33 assumes that the display image 60 is an original planar (no tilt) image in step S140. During contact, the driver can perform original screen operations, that is, selection and determination of each menu 61 and various icons 62 by sliding or touching the finger.

On the other hand, if it is determined in step S50 that the operator is a passenger, the operation control unit 33 performs screen display settings for the passenger in step S52. The screen display setting for the passenger seat first means that the display image 60 is an image provided with a dedicated content 64 that allows the passenger seat passenger to directly operate the basic image for the driver. It is set to be. When the operation state of the passenger's finger is close, as shown in FIG. 11 (in the left frame), the display image 60 displayed in a three-dimensional manner is actually displayed in steps S180, S200, and S220. The image is tilted toward the front passenger seating the finger. Note that the closer the passenger's finger is to the operation surface 32, the smaller the inclination of the stereoscopic image, and the farther the finger is from the operation surface 32, the larger the inclination of the stereoscopic image is displayed. When the passenger is in the vicinity, the main image can be switched by the menu 61 in the display image 60 by a finger operation (gesture such as flick).

The passenger seat exclusive content 64 corresponds to an example of the operation image unit of the present disclosure. For example, in the main image for an air conditioner, the passenger seat side temperature can be set independently. It is an icon for setting the seat side temperature. The content 64 includes, for example, an upper temperature setting unit, a temperature rise setting unit, a maximum temperature setting unit, a lower temperature setting unit, a temperature lowering setting unit, and a minimum temperature setting unit with respect to the current set temperature. Etc. are provided.

At this time, the passenger's seat intuitively knows that the current display image 60 is based on the input of the passenger's seat himself because the three-dimensional display image 60 is tilted in the direction of his / her own. Can know. At the same time, as in the first embodiment, the smaller the inclination of the display image 60 displayed in a three-dimensional manner, the closer the finger is to the operation surface 32 (the proximity 1 side), and vice versa. It is possible to intuitively know that the finger is at a position away from the operation surface 32 (proximity 3 side).

If the operation state of the passenger's finger is in contact, the operation control unit 33 assumes that the display image 60 is an original flat (no tilt) image in step S140. During the contact, the passenger can slide or touch the finger to perform the original screen operation, that is, selection and determination of each menu 61, various icons 62, and further the content 64.

As described above, in the present embodiment, the operator's target is the driver and the passenger seat, and the finger operation on the operation surface 32 is performed. The display image 60 to be displayed is tilted toward the operator who actually performed the finger operation. Therefore, the operator can intuitively understand that the current display image 60 is based on the input of the operator himself, and may be wondering whether the driver or the passenger in the passenger's seat is operating. The operability can be improved.

In addition, when the passenger seat is operated by a finger, a dedicated content 64 that can be directly operated by the passenger seat is displayed in the display image 60. Thereby, the operability of the passenger seat can be improved.

(Other embodiments)
In each of the above-described embodiments, as the operation state of the finger, in the proximity state, three sections of proximity 1, proximity 2, and proximity 3 are provided. Proximity or four or more proximity may be set as appropriate.

Further, in the first embodiment, when the operation state of the finger is in proximity, when the display image 60 is displayed in a three-dimensional manner, the display image 60 is tilted so as to face the operator side. Alternatively, the image may be an original rectangular shape without inclination.

In this case, as the division for the proximity 1, proximity 2 and proximity 3, it can be dealt with by changing the distance between the original image portion of the stereoscopic display image 60 and the shadowed portion, for example. That is, in the case of the proximity 1, if the distance between the original image portion and the shadowed portion is reduced (set to a predetermined value), and the distance is increased as the shift to the proximity 2 and the proximity 3 is made, good.

In the second embodiment, the temperature setting content 64 in the air conditioner is used as the dedicated operation image unit for the passenger seat. However, the present invention is not limited to this, and the temperature setting content for the seat heater is not limited thereto. Or a content for setting the position of the seat position.

In addition, although the capacitive touch sensor 31 is used as the detection unit (an example of the detection means), the detection unit is not limited to this, and may be another pressure-sensitive touch sensor or the like.

Further, a push switch may be provided in the

remote operation device

100 or 100A, and when the content (icon or the like) selected by the finger operation is determined, it may be determined by pressing this push switch.
